Abstract
The second graphic data for display is obtained by performing reduction processing using over-sampling on the first graphic data corresponding to the image generated by performing texture mapping processing based on polygon data, thereby the resolution of an image comprising the first graphic data is enhanced maintaining the memory capacity minimized, thus the display resolution of the second graphic data is enhanced. Further, each pixel of an component of the second graphic data is the average value of adjacent four pixels in the first graphic data, hence, for example, a 16 bit direct color image is equivalent to a 24-bit full color image.
Claims13
A two-buffer graphic data generation device comprising:
- a frame memory having a first memory region for storing first graphic data corresponding to a prescribed image and a second memory region for storing second graphic data obtained by reducing said first graphic data, said second graphic data being output as a video signal to be displayed on a display device;
- and
- a graphic data generation circuit for generating the second graphic data for display by performing reduction processing on the first graphic data read out from the first memory region of said frame memory during a display blanking period of said display device.
A two-buffer graphic data display system comprising:
- a graphic data generation circuit for generating first graphic data obtained by performing texture mapping processing on polygon data and for generating second graphic data obtained by performing reduction processing on said first graphic data;
- a frame memory for storing said second graphic data;
- and
- display means for displaying the second graphic data stored in said memory,
- wherein said graphic data generation circuit performs said reduction processing during a display blanking period of said display device.
A two-buffer graphic data generation method comprising the steps of:
- generating first graphic data corresponding to a prescribed image obtained by performing texture mapping processing on polygon data;
- generating second graphic data for display obtained by performing reduction processing on said first graphic data;
- displaying the second graphic data on a display means;
- and
- performing said reduction processing during a display blanking period of said display device.
